8 Claims.

This invention relates to an oven burner assembly, and particularly to an improved support therefor, such as may Aloe used to advantage in a gas cooking range for the home or elsewhere.

In the construction and operation of a gas cooking range it is important to simplify and expedite the assembly of the parts, and also to facilitate their dissassembly whenever occasion therefor arises. To accomplish these ends is a primary object of this invention. For this purpose we utilize certain parts which may be set in place with proper manipulations, and without the use of any tools or fastening elements. A pair of rods extending crosswise of the oven near its base constitute the support for the oven burner assembly and the construction and mounting of these rods is an important feature of this invention.

Other objects and advantages will also appear hereinafter from the detailed description of the accompanying drawing wherein is illustrated a suggestive embodiment of this invention in the manner following:

Figure 1 is a fragmentary front elevation of a gas cooking range with certain parts thereof broken away to exhibit in elevation the front rod support for the oven burner assembly a portion of which appears in section;

Fig. 2 is a vertical section, taken on line 2-2 of Fig. 1;

Fig. 3 is an elevational detail of one of the supporting rods together with the wall supports therefor, the latter being shown in section;` and Fig. 4 which is a view similar to Fig. 2, although mostly in elevation, shows the units of the oven burner assembly in slightly separated relation.

In the illustrated stove there is an oven cornpartment having spaced side walls Ill and I I between which is positioned an oven burner assembly comprising a burner A, a burner baffle B, andan oven bottom C'. This assembly is supported upon a pair of crosswise rods D extended between the side walls I and II. These rods are disposed at a common level, one toward the front and the other toward the rear of the compartment. Since these rods are alike, a detailed description of but one will be given.

Each rod, formed of wire or the like, is formed with a drop center portion I5 which extends for the major portion of the length of the rod to join with its opposite end portions through inclined connecting sections I6. Normally the rod is rotatively disposed as shown in Fig. 1. The rod is also provided with a short center downset at I1, and its two ends I8 are inclined angularly upwardly, as shown. The walls I0 and II are each provided with a hole 20, one opposite the other, for receiving one end of each rod, and each wall is crimped outwardly at a just above its hole and inwardly at b just below its hole (see Fig. 3) the two crimps -being substantially parallel to provide in effect an axis for the hole that is inclined downwardly and outwardly.

In assembling each rod into its operative position, the rod is first turned through as shown in Fig. 3, so that the axis of one angled end I8 is aligned with that of the hole 20 in the wall III wherein it is to be received; the angled end of the rod is then advanced into and through the hole, and the rod is then manipulated properly to perform similarly the operation of inserting its opposite angled end in the hole 20 in the other wall I I. When done, the rod is allowed to swing around by gravity so that its downset central portion I1 will be suspended downwardly and its angled ends I8 inclined upwardly and transversely of the axes of the two holes 20 (see Fig. 1). Each rod, when so positioned, is manifestly prevented from endwise movement and so is effectively locked in place; when turned around through 180 again, counter to the gravity force acting on its drop center, the rod is free to be successively disengaged at its two ends from the supporting holes of the walls I0 and I I.

The two rods D provide a support from which may be suspended the burner A which. as here` shown. comprises a hollow casting having at iti front end a lateral opening 25 in connection with a manifold 26 through which air is. drawn into the burner to support combustion of the fuel. A plurality of burner openings 21 are provided along opposite sides of the burner where combustion takes place, the llames then playing out'-v wardly in the usual way.

At the front end of the burner casting is an upwardly extended arm 30 terminating in a downwardly facing hook 3i which is arranged to engage the central downset portion I1 of the forward rod D. A similar arm 32 is extended upwardly and rearwardly from the proximate end of the burner to terminate in a downwardly facing hook 33 for engaging with the central downset portion I1 of the rod D lying to the rear. It will -be noted that the burner, when so supoprted, is rested loosely on the central downset portions of the two rods and that the arms 30 and 32 are of substantial width so that each will engage its supporting rod for substantially the full length of its central downset portion I1. As a result, the burner is prevented from ,shifting endwise 3 along either rod, and so is maintained nxedly in a position centrally thereof, although readily disengageable therefrom.

The baille B is in the form of a plate which by preference is provided with a depending rib 35 extending from front to rear in its medial region to provide reinforcement therefor. The side edge portions 36 of the baille plate may also be angled upwardly (see Fig. 1) for a similar purpose. These angled edge portions substantially engage with the rods at the junctures of their connecting sections I6 with their drop center portions l so as to confine the baille platevagainst shifting movement endwise of the rods. To locate the baille plate properly and prevent longitudinal shifting thereof, we have struck downwardly therefrom a pair of ears 31 near the front and a similar pair of ears 38 near the rear, these two pairs of ears lying just forwardly and rearwardly of the two rods D when assembled therewith. The baille plate is arranged to rest upon the drop center portion l5 `of each supporting rod and be confined thereupon against lateral or longitudinal shifting movement. In this position the baffle plate is elevated above the burner A a distance sumcient for adequate spread of the flames issuing from the jet openings 21 s o as to distribute the heat over a wide area of the baffle plate.

The oven bottom C is also in the form of a metal plate having depending marginal flanges llt which at the front extends outwardly and downwardly for an enhanced distance in the form of an apron 4|. This apron overlies the proximate edge of the baille plate B and also the forward supporting rod D so that their presence is effectively concealed. The lower edges of the depending marginal flanges rest on the two rods D (see Fig. 1) at four points to the outside of their connecting sections I6, and thereby support the plate C in elevated position above the baffle plate B. This plate constitutes the bottom for `the oven which is heated by the flames issuing from the burner A, and which is desirably inclined downwardly very slightly to a low vpoint near its center. Heal-,transferred through and past the baille plate is effectively distributed to the under side of the oven bottom plate C which may be fixedly secured in place by fastening means (not shown) in engagement with any convenient part of the range structure.

' From the preceding description, it will be evident that whenever any adjustment or replacement of the burner or parts associated therewith is required, the operation of doing so is very simple indeed. It involves merely removal of 'the oven bottom. lifting of the baille plate from Aits supported position upon the rods and, if necessary, lifting of the burner from the supporting rods preliminary to its removal from the oven compartment. The rods may also be taken out, if it be necessary, by a reversal of the simple operation already described. When assembly has been completed, as indicated in Figs. 1 and 2 vof drawing, the parts will remain flxedly in itheir proper positions due, among other things, to the drop center portions I5 of the supporting rods which support the baille plate B and which are provided with central downset portions |1 from which the burners are suspended.
